2 Factors that affect health Smallest Impact Largest Impact Counseling & education Clinical interventions Long-lasting protective interventions Changing the context To make individuals default decisions healthier Socioeconomic factors Examples Eat healthy, be physically active Medication for high blood pressure, high cholesterol, diabetes Immunizations, brief intervention, cessation of treatment, colonoscopy Fluoridation, g trans fat, iodization, smoke-free laws Poverty, education, housing, inequality Number of Infections Antibiotic Resistance Initiative could reduce many infections Projected burden of healthcare-associated invasive MRSA, healthcare-associated CDI, healthcare-associated CRE, and hospital-onset MDR Pseudomonas infections 4, 35, 3, 25, 2, 15, 1, 5, Maintaining status quo Aggressive multisectoral intervention Over 5 years prevention will result in: > 1/2 million AR infections averted Thousands of AR infection attributable deaths averted Billions in medical costs averted $5. 5,,, Bn 4,5,, Attributable medical costs ($ in billions) $4. 4,,, Bn 3,5,, $3. 3,,, Bn 2,5,, $2. 2,,, Bn 1,5,, $1. 1,,, Bn 5,, $ 2

Globally, the TB mortality rate fell ~1/3 between 199 and TB + HIV-TB TB Only HIV-TB Only Rate per 1, population per year Includes TB deaths in both HIV-negative and HIV-positive people. 3
